Trouble loading realm objects after sync: realm is empty despite writing

When my program signs up a user, it authenticates the username and password using the following method:

func authenticate(username: String, password: String, register: Bool, callback: @escaping (NSError?) -> Void) {

    let credentials = SyncCredentials.usernamePassword(username: username, password: password, register: register)

    SyncUser.logIn(with: credentials, server: Constants.syncAuthURL) { user, error in

        DispatchQueue.main.async {

            if let user = user {
                setDefaultRealmConfiguration(with: user)
            }

            // handle error

        }
    }
}

The setDefaultRealmConfiguration(with: user) looks as follows:

public func setDefaultRealmConfiguration(with user: SyncUser) {

    print("DEFAULT REALM CONFIG SET")

    Realm.Configuration.defaultConfiguration = Realm.Configuration(
        syncConfiguration: SyncConfiguration(user: user, realmURL: Constants.syncServerURL!),
        objectTypes: [UserData.self, Achievement.self])
}

Am I correct to assume that this is enough for me to create a realm let realm = try! Realm() and write/read from it after authenticating a user? Because after writing to the realm, logging out a user SyncUser.current.logOut(), then signing back in using authenticate, all written information is seemingly lost. The information is not much, just a few strings (nevertheless, I implemented a timer to see if that worked - it didn't).

Here are the logs:

DEFAULT REALM CONFIG SET 

WRITING DATA...

Turns out, I was initializing an instance of Realm before doing the default realm configuration... this meant I was looking into another (offline) realm rather than the one where I did the writing. Redeclaring the realm instance inside the authentication function fixed the problem.
